5. The following- Table of the local errors on Mean Time of an excellent 

 eight- day Chronometer, by Barraud, is given to shew that no available me- 

 thods were neglected, but owing to an unexpected irregularity in the rate 

 of the watch, they are not of the value I anticipated. The Immersions or 

 Emersions of Jupiter's Satellites that were observed have been already 

 published, being used to fix the longitude of the first Meridian of the 

 survey. It was considered that the errors of such results as a comparison 

 with the Nautical Almanac could furnish, would be much greater than those 

 even of the imperfect methods finally resorted to.
